Dr Rowan Martin

PhD (Sheffield, UK)
BSc Hons (East Anglia, UK)

Activities and research interests:

Rowan’s research interests lie in the fields of behavioural ecology and conservation, specifically understanding the evolutionary and ecological drivers of behaviour, and their implications for the persistence of populations. Rowan also has a general interest in the conservation of parrots (Psittacidae) and is currently the Manager of the World Parrot Trust’s Africa Conservation Programme.

Rowan was based at the Fitz between 2009 and 2013 where he held a DST/NRF Centre of Excellence Post-doctoral Fellowship. His primary research focus was on understanding the role of behavioural plasticity in mediating the impacts of climate change on birds. This research used bird communities in the hot, arid ecosystems of the southern Kalahari to investigate the implications of microclimate use for desert birds, and a long-term dataset on reproduction in a range-expanding raptor population to investigate the demographic implications of phenological plasticity and mating decisions. Rowan continues to collaborate, co-supervise students and assist in the development of the 'Hot birds' research programme with Dr Susie Cunningham.

Rowan’s interest in parrot conservation developed during his doctoral studies on the drivers of mating systems in globally-threatened Yellow-shouldered Amazon parrots (University of Sheffield, UK). This research led to the development of a locally-based NGO (Echo) implementing conservation actions.

In his role as manager of the World Parrot Trust's Africa Conservation Programme, Rowan is responsible for overseeing research, evidence-based actions and outreach initiatives in support of parrot conservation throughout the African region. Direction for the programme is taken from a recent review of research and conservation priorities for parrots in Africa and Madagascar. This review was co-ordinated by Rowan on behalf of the International Ornithologist’s Union Research Co-ordination Committee for parrots (IOU-RCCP). The programme currently includes projects located in South Africa, Zambia and Guinea-Bissau. Current research topics include the origins of disease outbreaks, the breeding behaviour of threatened species, drivers of population and range changes and the impact of the wild-bird trade.
